There's something you missed in your own writings, Crius. You write that by spending 'the effort and time in training and growing their weaker members', the forgiving and mercyful island 'would be able to obtain its goals more quickly'. Taking time makes something slower, not quicker. I've heard once that the Sinistar has many ways of training the weaker members of his guild, but they all include rigid discipline. No infernal could have surpassed newbiehood if they were not properly trained. Sinistar's hypothesis only deals with the fact that the disciplined island would indeed work much faster than the non-disciplined island, which in a macroscopic point of view is correct.

Yet, I also prefer balance in my thought, and I have come up with a different conclusion for a simpler situation within the global situation described by the Sinistar. One day, after both groups of islanders have started constructing their boat, it just happens that the same task must be accomplished on both islands: a large log must be carried from the forest to the construction site of the ships of the respective islands. And, on both islands, it just happens that the same ammount of people are available for the task: two strong, and one weak (on each island), none knowing much about their strength in comparison to each of the other two. On the disciplined island, the three men will head to the felled tree, and settle for giving each man a position that would allow all three to lift an equal ammount of weight. The weak man will prove incapable of doing so, and will soon drop with fatigue, and be - if not killed - at least left behind to pant. The two other strong men will not be able to lift the log on the
The two other strong men will not be able to lift the log on their own, so they will end up dragging it to the 'shipyard'. On the forgiving island, the three men will pick the log up in the same fashion at first, equally distributing the weight to each person. When the weaker man starts to whine, or pant, etc., the stronger men will allow him to shift his position in order to have less to carry, and maybe even to take a short rest, but they will continue walking with the log in their arms, and they will arrive at the shipyard faster than the two strong men on the disciplined island. That makes for a microscopic point of view which points to a completely different conclusion than the macroscopic point of view encompassed in the same global situation.
